How have you done in high school math? Are you on track to take calculus as a senior? Some people are pretty good at math, but don’t score as well as they should on standardized tests. I’d say that CS generally requires a fair amount of math - certainly dicscrete math and some calculus and the kind of logical thinking required is basically math related. What sort of programming experience do you have?
It looks like Carnegie Mellon requires 4 real math courses: https://www.csd.cs.cmu.edu/education/bscs/currsequence_14.html My son loved CMU, but it will probably be too much of a reach for you. I echo all the suggestions especially the lists in #13 and #14.
